Description
Technical field
The present invention relates to a kind of air cleaning unit, particularly relate to a kind of purifying formaldehyde device.
Background technology
Air purifier refers to the pollutant that can adsorb, decompose or transform in various air, effectively improves the product of indoor air clean degree.At home, medical treatment, industrial circle all have application, the field main product that is market with the Household Air Purifier of unit class at home.Topmost function removes the particle in air, comprises anaphylactogen, indoor PM2.5 etc., can also solve volatile organic matter air pollution problems inherent in the indoor because finishing or other reasons cause, the underground space, car simultaneously.Because the release of the space Air Contamination thing of relative closure has persistence and probabilistic feature, therefore using air purifier to purify the air of a room is one of internationally recognized method improving IAQ.
Remove technology according to air purifier for particulate in air, mainly contain mechanical filter net type, electrostatic electret filter net type, high-voltage electrostatic dust-collecting, anion and plasma method etc.
Mechanical filter generally catches particulate mainly through following 4 kinds of modes: directly tackle, inertial collision, Blang's diffusion mechanism, screening effect, to fine particle thing collecting effect, good but windage is large for it, and in order to obtain high purification efficiency, the resistance of filter screen is larger, and filter screen needs densification to cause service life reduction, need periodic replacement.
High-voltage electrostatic dust-collecting utilizes high-voltage electrostatic field to make gas ionization thus makes dust particles be adsorbed onto collecting method on electrode, though its windage little to larger particles and fiber trapping weak effect, can electric discharge be caused, and cleaning trouble time-consuming, easy generation ozone, forms secondary pollution.
The operation principle that anion and plasma method remove indoor particle pollutant is similar, all by making the particle in air charged, coalescent formation larger particles and sedimentation, but in fact particle does not remove, just be attached on neighbouring surface, easily cause airborne dust again.
Electrostatic electret capacitance filter screen, relative mechanical formula is filtered and only effectively can be removed the particle of more than 10 microns, and when the particle diameter of particle removes to 5 microns, during the scope of 2 microns of even sub-micron, efficient mechanical filtration system will become costly, and windage can significantly increase.Filtered by electrostatic electret air filting material, very high capture rate can be reached with lower energy resource consumption, have the advantage of the low windage of electrostatic precipitation simultaneously concurrently, but without the need to the voltage of external volt up to ten thousand, therefore can not ozone be produced, and consist of polypropylene material due to it, easily abandon process.
It should be noted that the clarifier of most brand all can exaggerate its effect in sale publicity, some clarifier is declared can " effectively catch " tens kinds of particles.In the face of the function of miscellaneous market brand and complexity, consumer has kind of a sensation of looking at flowers in a fog.For this reason, expert reminds consumer when screening product function, the time candidate board guaranteed product that can selecting, or selects according to the sales volume of product.In country's " air purifier " relevant criterion, air purifier is defined as and " from air, is separated and removes the equipment of one or more pollutants.Pollutant in air is had to the device of certain removal ability.Mainly refer in room use monomer-type air purifier and centralized air ventilation system in modular air clarifier.
Purifying formaldehyde device belongs to the one in air purifier, and the efficiency that the purifying formaldehyde device of prior art much all also exists purifying formaldehyde is not enough, the degree of purification of PARA FORMALDEHYDE PRILLS(91,95) can not carry out the problem that detects while purification.
